Okay, so how do these things even work; or do they even?
It seems like just a consumable that has the same effect as the "auto-finish’ check box. If you unchecked that box, the keys do NOT “automatically” open, I have to disarm it manually, and then the key icon will pop up on the screen, as if it’s done it on its own (even though I physically had to disarm it myself).
So am I misunderstanding its function? Does it instead stop me from the negative affects of the trapped chests? Cause I’m beyond confused on why anyone would waste their resources on getting this hunk of junk.
